Non-linear SSI analysis in time domain using coupled FEM–SBFEM for a soil–pile system

摘要: The scaled boundary finite-element method (SBFEM) coupled with the (FEM) is increasingly being employed to study soil–structure interaction (SSI) problems. However, most of FEM–SBFEM models for dynamic SSI analysis include only linear behaviour soil in near field. In present work, a scheme presented time domain non-linear analysis. An advanced plasticity-based model, namely hierarchical single-surface (HiSS)-δ0, incorporated simulate non-linearity. A three-dimensional single pile–soil system solved externally applied load as well ground excitation. parametric done gain insight into effects stiffness and intensity loading on response by calculating its impedances kinematic factors. Also, displacement at pile head due El Centro earthquake calculated a...
